TECHNICAL FIELD

This disclosure relates to document tools and, more particularly, to tools for processing and interacting with a document.

BACKGROUND

Many documents utilize a hierarchical organizational structure to improve comprehension and to allow for internal cross-referencing between the various sections of the document. While the hierarchical structure of a document may be useful for improving comprehension of the subject matter of the document, the management of the hierarchical structure during creation and editing of the document can present many challenges. For example, during editing of the document elements may be added at various levels of the hierarchical structure, new levels of hierarchy may be created and/or levels of the hierarchy may be removed, and elements may be moved within and/or between hierarchical levels. Such changes may impact portions of the document other than those being directly edited. The impacted portions of the document may be required to be updated in response to the edits, which may complicate the creation and editing process for the document.

DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS

Referring to FIG. 1, there is shown document process 10. For the following discussion, it is intended to be understood that document process 10 may be implemented in a variety of ways. For example, document process 10 may be implemented as a server-side process, a client-side process, or a server-side/client-side process.

For example, document process 10 may be implemented as a purely server-side process via document process 10 s. Alternatively, document process 10 may be implemented as a purely client-side process via one or more of client-side application 10 c 1, client-side application 10 c 2, client-side application 10 c 3, and client-side application 10 c 4. Alternatively still, document process 10 may be implemented as a server-side/client-side process via event monitoring process 10 s in combination with one or more of client-side application 10 c 1, client-side application 10 c 2, client-side application 10 c 3, and client-side application 10 c 4.

Accordingly, document process 10 as used in this disclosure may include any combination of document process 10 s, client-side application 10 c 1, client-side application 10 c 2, client-side application 10 c 3, and client-side application 10 c 4.

According to various implementations and embodiments, document process 10 may provide various functionality. For example, in some embodiments, document process 10 may generally process a document to determine a hierarchical structure associated with one or more portions of the document. In some embodiments, document process 10 may generally process a document to generate a linkable map of the document based on, at least in part, a hierarchical structure of the document. In an example embodiment, the linkable map of the document may be utilized to, e.g., navigate the document. In still further embodiments, document process 10 may allow for groups or classes of items within a document to be modified based on, at least in part, the modification of one item included within a group or class. Various additional and/or alternative embodiments and/or features may also be implemented. Further, various features and embodiments may be implemented alone and/or in combination with one another.

Document process 10 s may be a server application and may reside on and may be executed by computing device 12, which may be connected to network 14 (e.g., the Internet or a local area network). Examples of computing device 12 may include, but are not limited to: a personal computer, a server computer, a series of server computers, a mini computer, a mainframe computer, or a dedicated network device.

The instruction sets and subroutines of document process 10 s, which may be stored on storage device 16 coupled to computing device 12, may be executed by one or more processors (not shown) and one or more memory architectures (not shown) included within computing device 12. Examples of storage device 16 may include but are not limited to non-transitory computer readable mediums, such as a hard disk drive; a tape drive; an optical drive; a RAID device; an NAS device, a Storage Area Network, a random access memory (RAM); a read-only memory (ROM); and all forms of flash memory storage devices.

Network 14 may be connected to one or more secondary networks (e.g., network 18), examples of which may include but are not limited to: a local area network; a wide area network; or an intranet, for example.

Examples of client-side applications 10 c 1, 10 c 2, 10 c 3, 10 c 4 may include but are not limited to a web browser, a game console user interface, a television user interface, or a specialized application (e.g., including an application running on a mobile platform). The instruction sets and subroutines of client-side application 10 c 1, 10 c 2, 10 c 3, 10 c 4, which may be stored on storage devices 20, 22, 24, 26 (respectively) coupled to client electronic devices 28, 30, 32, 34 (respectively), may be executed by one or more processors (not shown) and one or more memory architectures (not shown) incorporated into client electronic devices 28, 30, 32, 34 (respectively). Examples of storage devices 20, 22, 24, 26 may include but are not limited to: hard disk drives; tape drives; optical drives; RAID devices; random access memories (RAM); read-only memories (ROM), and all forms of flash memory storage devices.

Examples of client electronic devices 28, 30, 32, 34 may include, but are not limited to, data-enabled, cellular telephone 28, laptop computer 30, personal digital assistant 32, personal computer 34, a notebook computer (not shown), a server computer (not shown), a gaming console (not shown), a data-enabled television console (not shown), and a dedicated network device (not shown). Client electronic devices 28, 30, 32, 34 may each execute an operating system.

Users 36, 38, 40, 42 may access event process 10 directly through network 14 or through secondary network 18. Further, event process 10 may be accessed through secondary network 18 via link line 44.

The various client electronic devices (e.g., client electronic devices 28, 30, 32, 34) may be directly or indirectly coupled to network 14 (or network 18). For example, data-enabled, cellular telephone 28 and laptop computer 30 are shown wirelessly coupled to network 14 via wireless communication channels 46, 48 (respectively) established between data-enabled, cellular telephone 28, laptop computer 30 (respectively) and cellular network/bridge 50, which is shown directly coupled to network 14. Further, personal digital assistant 32 is shown wirelessly coupled to network 14 via wireless communication channel 52 established between personal digital assistant 32 and wireless access point (i.e., WAP) 54, which is shown directly coupled to network 14. WAP 54 may be, for example, an IEEE 802.11a, 802.11b, 802.11g, 802.11n, Wi-Fi, and/or Bluetooth device that is capable of establishing wireless communication channel 52 between personal digital assistant 32 and WAP 54. Additionally, personal computer 34 is shown directly coupled to network 18 via a hardwired network connection.

Referring also to FIG. 2, according to an embodiment, document process 10 may identify 100 a plurality of indicators of hierarchy within a document. Document process 10 may also determine 102 a hierarchical level associated with each of the plurality of indicators. Further, document process 10 may associate 104 one or more portions of the document with a respective hierarchical level associated with each of the plurality of indicators.

For example, document process 10 may identify 100 a plurality of indicators of hierarchy within a document. The document may include a document that does not include meta-data or the like indicating a hierarchical structure of the document. Rather, the hierarchy of the document may be indicated by textual content and/or textual structure of the document. For example, the plurality of indicators of hierarchy within the document may include textual features, such as numbers, lettered captions, and the like; and/or textual structure of the document, such as formatting attributes, and the like. An example of a document that may include indicators of hierarchy may include legal agreements. The document may include any text document, such as a document created with a word processing application, a text editor application, or any other suitable application that may be utilized for the creation of a text document.

In an embodiment, each of the plurality of indicators may include an itemizer. In general, an itemizer may include a sequence of characters that may identify a hierarchical position or level (i.e., may identify position within a hierarchical structure). Each itemizer may include one or more of a prefix, a stem, and a suffix. A first example of an itemizer may include “Article I”, wherein the prefix may include the characters “Article” (including the space character). The stem of the first example itemizer may include the character “I” and a suffix may not be included in the first example itemizer. A second example of an itemizer may include “Section 1.01.”. The prefix of the second example itemizer may include “Section 1.0”, (including the space character). The stem of the second example itemizer may include the character “1”, and the suffix of the second example itemizer may include the character “.”. A third example itemizer may include “c)”, which may not include a prefix and which may include the character “c” as the stem and the character “)” as the suffix. A fourth example itemizer may include “(i)”. In this fourth example itemizer the characters “(” and “)” may respectively be the prefix and suffix, and the character “i” may be the stem. It will be appreciated that various additional and/or alternative itemizers may also be utilized, wherein the itemizers may include a sequence of characters that may provide an indicator of hierarchical position or level.

Document process 10 may also determine 102 a hierarchical level associated with each of the plurality of indicators. For example, each of the plurality of indicators may represent and/or indicate a respective position within a hierarchical structure. Document process 10 may determine 102 the hierarchical level associated with each of the indicators, and thereby determine a respective position associated with each of the plurality of indicators within a hierarchical structure. In an example embodiment, determining 102 the hierarchical level associated with each indicator may include interpreting 106 at least a portion of each of the plurality of indicators to determine a numbering style associated with each indicator and a numerical value associated with each indicator. In some embodiments, document process 10 may interpret 106 at least the stem of an itemizer to determine a numbering style associated with the itemizer and to determine a numerical value associated with the itemizer.

Continuing with the foregoing, and referring to the previously described example itemizers (i.e., “Article I”, “Section 1.01.”, “c)”, and “(i)”), document process 10 may interpret 106 the stem of the first example itemizer (“I”) to determine a numbering style and a numerical value. In such an embodiment, document process 10 may interpret 106 the stem “I”, as an upper case Roman numeral having a numerical value of one. Alternatively, document process 10 may interpret 106 the stem “I” as an upper case Latin letter having a numerical value of nine (e.g., based on “I” being the ninth letter of the Latin alphabet). Similarly, document process 10 may interpret 106 the stem “1” of the second example itemizer as an Arabic numeral having a numerical value of one. Further, document process 10 may interpret 106 the stem “c” of the third example itemizer as a lower case Latin letter having a numerical value of three. Alternatively, document process 10 may interpret 106 the stem “c” as a lower case Roman numeral having a numerical value of 100. As with the first example itemizer, document process 10 may interpret 106 the stem “i” of the fourth example itemizer in a similar manner as the first example itemizer (i.e., either as a lower case Roman numeral having a numerical value of one or as a lower case Latin letter having a numerical value of nine). In an embodiment in which an indicator of hierarchy (e.g., an itemizer) may include multiple possible interpretations, document process 10 may flag the indicator as having multiple possible interpretations and may determine an interpretation in a manner described in detail below. Additional and/or alternative numbering styles and associated numerical values may be utilized in connection with one or more of the plurality of indicators of hierarchy included within the document.

In addition to interpreting 106 a stem of an itemizer to determine a numbering style and/or a numerical value associated with the itemizer, in some embodiments document process 10 may also interpret one or more of the prefix and the suffix, e.g., to determine a relative hierarchical position of the itemizer based on, at least in part, the prefix and/or the suffix. Relative hierarchical position indicated by the prefix and/or suffix may be based on, for example, one or more rules and/or preferences that may be established, and/or based on, at least in part, an indication received from a user. For example, in an embodiment, a rule may be established wherein an agreement may be divided into a plurality of articles, and each of the articles may be divided into a plurality of sections. Sections may be further divided into, e.g., subsections, paragraphs, clauses, etc.). Various additional and/or alternative embodiments may be implemented.

In an example embodiment, determining 102 a hierarchical level associated with each of the plurality of indicators may include determining 108 if a current indicator follows a preceding indicator. In an embodiment, a preceding indicator may include an immediately preceding indicator (i.e., not including an intervening indicator in the document). A current indicator may follow a preceding indicator if, for example, document process interprets 106 the current indicator as having (1) the same prefix and suffix as the preceding indicator, (2) the same numbering style as the preceding indicator, and (3) a numerical value that is one greater than that of the preceding indicator. Consistent with the present disclosure, a prefix and suffix of a current indicator may be the same as the prefix and suffix of a preceding indicator if the prefix and suffix exactly match or approximately match based on, for example, a string edit distance (e.g., the Levenshtein distance).

For example, and referring also to FIG. 3, a portion of an example embodiment of a document (e.g., agreement 150) is generally depicted. As shown, agreement 150 may generally include a plurality of provisions (e.g., provisions 152-174) of Article I. Each of example provisions 152-174 may include text of agreement 150 and may be identified by a textual indicator (e.g., respective indicators “(a)”, “(b)”, “(c)”, “(d)”, “(e)”, “(f)”, “(g)”, “(h)”, “(i)”, “(ii)”, “(i)”, “(j)”), which may represent a hierarchical level of each provision within agreement 150. In an example embodiment, document process 10 may determine that the indicator “Article I” may define a hierarchical root, e.g., which may be a primary, or top, hierarchical level, e.g., based on one or more defined rules and/or preferences. Further, document process 10 may determine a hierarchical level associated with indicator “(a)” including interpreting 106 indicator “(a)” as including respective prefix and suffix “(” and “)” and stem “a”. Further, document process 10 may interpret 106 the stem “a” as having a lower case Latin alphabetical numbering style and a numerical value of one. Further, document process 10 may determine 108 that current indicator “(a)” (i.e., document process 10 may be currently determining 102 the hierarchical level of indicator “(a)”) may begin a new list within a hierarchical level.

In a generally similar manner, document process 10 may determine 102 the hierarchical level associated with indicator “(b)” associated with document provision 154. Determining 102 the hierarchical level associated with indicator “(b)” may include interpreting the stem “b” as having a lower case Latin alphabetical numbering style and a numerical value of two. Further, document process 10 may determine 108 that current indicator “(b)” (i.e., the indicator for which document process 10 may currently be determining a hierarchical level) may follow a preceding indicator. Consistent with the illustrated example, the preceding indicator may include indicator “(a)” (e.g., indicator “(a)” may be the immediately preceding identified 100 indicator). Consistent with the illustrative example, indicator “(b)” may include a prefix and a suffix which may match the prefix and suffix of indicator “(a)”. Further, indicator “(b)” may have a lower case Latin alphabetical numbering style, which may be the same as indicator “(a)”. Further, indicator “(b)” may have a numerical value of two, which may be one greater than the numerical value of indicator “(a)”. Accordingly, document process 10 may determine that indicator “(b)” may follow indicator “(a)”.

In a manner generally similar to the above-discussed embodiment, document process 10 may determine 108 that indicator “(c)”, associated with provision 156, may follow indicator “(b)” associated with provision 154. Further, document process 10 may similarly determine that indicators “(d)”, “(e)”, “(f)”, “(g)”, “(h)”, and “(i)”, respectively associated with provisions 158-168, may follow one another in an ordered sequence residing in a common hierarchical level beneath root hierarchical level “Article I”. Continuing with the illustrative embodiment depicted in FIG. 3, document process 10 may interpret 106 indicator “(ii)”, associated with provision 170, as having a lower case Roman numeral numbering style and a numerical value of two. Further, document process 10 may determine that indicator “(ii)” does not follow the preceding indicator (i.e., indicator “(i)” associated with provision 168, being the immediately preceding indicator in agreement 150). For example, document process 10 may have interpreted 106 indicator “(i)” associated with provision 168 as having a lower case Latin alphabetical numbering style and a numerical value of nine, whereby indicator “(i)” associated with provision 168 may follow indicator “(h)”, which may be interpreted 106 as having a lower case Latin alphabetical numbering style and a numerical value of eight. Accordingly, the numbering style of indicator “(ii)” (e.g., lower case Roman numeral numbering style) may not match the interpretation of the numbering style of indicator “(i)” associated with provision 168. Additionally, the numerical value of indicator “(ii)” (e.g., two) may not be one greater than the interpreted 106 numerical value of indicator “(i)” associated with provision 168 (e.g., which may have a numerical value of nine).

In response to determining that the current indicator (e.g., indicator “(ii)”) does not follow the preceding indicator (e.g., indicator “(i)” associated with provision 168), document process 10 may determine 110 if the current indicator follows an ancestor indicator. An ancestor indicator may include any previously identified 100 indicator included under the rood hierarchical level (e.g., associated with the indicator “Article I” in the illustrated example). In some embodiments, an ancestor indicator may include an identified 100 previous indicator at a higher hierarchical level than the preceding indicator (e.g., at a hierarchical level closer to the root level than the preceding indicator). Consistent with the illustrated example, document process 10 may determine 110 that current indicator “(ii)” does not follow an ancestor indicator (e.g., no previous indicator includes a lower case Roman numeral numbering style, a numerical value one less than indicator “(ii)”, and respective prefix and suffix “(” and “)”).

In an embodiment, document process 10 may determine 112 an alternative interpretation of the preceding indicator. Still continuing with the illustrated example, the preceding indicator (e.g., indicator “(i)” associated with provision 168) may include more than one interpretation. For example, document process 10 may determine 112 that in addition to including a lower case Latin alphabetical numbering style and having a numerical value of nine, indicator “(i)” associated with provision 168 may include an interpretation as having a lower case Roman numeral numbering style and a numerical value of one.

In an embodiment, document process 10 may determine 112 the alternative interpretation of indicator “(i)” in response to determining that indicator “(ii)” does not follow the preceding indicator and does not follow any ancestor indicator. In some embodiments, document process 10 may determine 112 the alternative interpretation of indicator “(i)” when interpreting 106 indicator “(i)”. In such an embodiment document process 10 may flag indicator “(i)” as including multiple interpretations (e.g., by associating metadata with indicator “(i)”, or via another suitable mechanism).

In an embodiment, determining 112 the alternative interpretation of the preceding indicator (e.g., indicator “(i)” associated with provision 168) may include determining if the alternative interpretation of the preceding indicator may include an interpretation as being a first item within a sequence, and/or an interpretation that the current indicator (e.g., indicator “(ii)”) may follow. According to an embodiment, document process 10 may set 114 the preceding indicator to the alternative interpretation, and may set 116 the current indicator to follow the preceding indicator. Continuing still with the illustrated example, indicator “(i)” associated with provision 168 may include the alternative interpretation of having a lower case Roman numeral numbering style and a numerical value of one. Document process 10 may set 114 the interpretation of indicator “(i)” to such an alternative interpretation. Further, document process 10 may set 116 the current indicator “(ii)”, to follow indicator “(i)” associated with provision 168, as document process 10 may interpret 106 indicator “(ii)” as having a numbering style that matches that of indicator “(i)” associated with provision 168 (i.e., lower case Roman numerals), as having a numerical value one greater (e.g., two) than that of indicator “(i)” associated with provision 168, and as having a prefix and suffix that match those of indicator “(i)” associated with provision 168.

Continuing with the illustrated example, document process 10 may interpret 106 indicator “(i)” associated with provision 172, as having either a lower case Roman numeral numbering style and a numerical value of one, or as having a lower case Latin alphabetical numbering style and a numerical value of nine. Document process 10 may further determine that indicator “(i)” associated with provision 172 does not follow the preceding indicator (i.e., indicator “(ii)”) based on either interpretation. Further, document process 10 may determine 110 that indicator “(i)” associated with provision 172 may follow an ancestor indicator. For example, document process 10 may determine 110 that an interpretation 106 of indicator “(i)” associated with provision 172 as having a lower case Latin alphabetical numbering style and a numerical value of nine (and respective prefix and suffix “(” and “)”) may follow ancestor indicator “(h)”, which may include an interpretation 106 as also having a lower case Latin alphabetical numbering style and a numerical value of eight (and respective prefix and suffix “(” and “)”). In an embodiment, determining 110 that indicator “(i)” associated with provision 172 follows an ancestor indicator may include determining 112 an alternative interpretation of indicator “(i)” associated with provision 172 (e.g., if an initial interpretation of indicator “(i)” was as having a lower case Roman numeral numbering style and a numerical value of one).

Document process 10 may associate 104 one or more portions of the document with a respective hierarchical level associated with each of the plurality of indicators. For example, as generally discussed above, indicator “(a)” may be associated with provision 152, indicator “(b)” may be associated with provision 154, indicator “(c)” may be associated with provision 156, indicator “(d)” may be associated with provision 158, indicator “(e)” may be associated with provision 160, indicator “(f)” may be associated with provision 162, indicator “(g)” may be associated with provision 164, indicator “(h)” may be associated with provision 166, indicator “(i)” may be associated with provision 168, indicator “(ii)” may be associated with provision 170, indicator “(i)” may be associated with provision 172, and indicator “(j)” may be associated with provision 174. In an embodiment, document process 10 may associate 104 the provision associated with each respective indicator with the hierarchical level associated with each indicator. Accordingly, each provision 152-174 may include a respective hierarchical level. In some embodiments, document process 10 may associate metadata including an indicator of hierarchical level with each provision. Other mechanisms for associating 104 one or more portions of the document with a respective hierarchical level associated with each of the plurality of indicators may similarly be utilized.

In an embodiment, a respective hierarchical level may be associated with each of the one or more portions of the document. In some embodiments, the hierarchical level may be included as an intrinsic property of each of the one or more portions of the document. In other embodiments, the hierarchical level may be associated with each of the one or more portions of the document, e.g., as metadata associated with each of the one or more portions of the document. The hierarchical level associated with each of the one or more portions of the document may include, for example, metadata indicating a relative hierarchical level of each of the portions of the document. In such an embodiment, the respective hierarchical level associated with each of the one or more portions of the document may be independent of any particular indicators of hierarchy or numbering style or system. Accordingly, in some embodiments, the relative hierarchical position of the one or more portions of the document may be dynamically adjusted in response to one or more portions of the document being added, deleted, and/or moved. As such, the determined hierarchical structure of the document may remain intact.

Referring also to FIG. 4, in another example embodiment, document process 10 may process 200 a document to associate a plurality of items within the document with a group. Document process 10 may also modify 202 a first item included within the group. Document process 10 may further modify 204 all other items in the group based on the modified first item.

According to an example embodiment, the document may include a legal agreement and/or another document type that may include a hierarchical structure. In such an embodiment in which the document may include a legal agreement and/or another document including a hierarchical structure, document process 10 may process 200 a document to associate a plurality of items within the document with a group in which the group may include a hierarchical group. Accordingly, processing 200 the document may include processing the document to associate 206 each of the plurality of items with one of a plurality of hierarchical groups. As such, document process 10 may generally process the document to group the plurality of items included within the document into one of a plurality of hierarchical groups.

For example, and referring also to FIG. 5, an example of a document is shown rendered in a user interface (e.g., user interface 250, that may be provided, at least in part, by document process 10). As shown, the document may generally include a plurality of provisions (e.g., provisions 252-272), which may be items within the document. Document process 10 may process 200 the document to associate 206 the various provisions of the document with one of a plurality of hierarchical groups. For example, document process 10 may process 200 the document to associate 206 provisions 252, 262, and 272 with a first level hierarchical group. In one embodiment, document process 10 may associate 206 provision 252 with a first level hierarchical group under a root hierarchical group Article I. Similarly, in an embodiment, document process 10 may associate 206 provisions 262 and 272 with a first level hierarchical group under a root hierarchical group Article II. Continuing with the above example, document process 10 may associate 206 provisions 254-256 and 264-266 with a second level hierarchical group (e.g., with provisions 254-256 being in a second level hierarchical group under provision 252, and with provisions 264-266 being in a second level hierarchical group under provision 262). Further, document process 10 may associate 206 provisions 268-270 with a third level hierarchical group (e.g., a third level hierarchical group under provision 266).

Processing 200 the document and/or associating 206 each of the plurality of items within the document with one of a plurality of hierarchical groups may include determining a hierarchical structure of the document, e.g., in a manner as generally described above (e.g., with reference to FIGS. 2 and 3). In an additional/alternative embodiment, the document may include structural information (e.g., in the form of metadata associated with the various provisions, etc.) that document process 10 may utilize for processing 200 the document.

In addition and/or as an alternative to associating the plurality of items with a hierarchical group, other groups may be utilized. For example, in an embodiment in which the document may include a legal agreement, the group may include defined terms within the legal agreement. The plurality of defined terms (e.g., a plurality of items within the document) may be identified and associated with the group including defined terms based on, for example, metadata associated with the defined terms (e.g., which may identify the items as being defined terms) and/or other common attributes of the items (e.g., formatting, such as the terms being in bold type, underlined, set in upper case letters, in title case, etc.). Document process 10 may associate the identified items with a group. Various items may be associated with various different groups.

Document process 10 may also modify 202 a first item included within the group. For example, formatting or other characteristics of the first item may be modified. In an example embodiment, document process 10 may receive 208 a request to modify the first item included within the group. For example, from within user interface 250, a user (e.g., user 36 operating personal computer 28) may select provision 258 (e.g., using onscreen pointer 274, which may be controlled by a pointing device, such as a mouse; not shown) by clicking (and/or otherwise selecting) provision 258. In the illustrated example, based upon, at least in part, the selection of provision 258, document process 10 may receive 208 a request to modify an item within a group that includes the third hierarchical level of the document.

In response to user 38 selecting provision 258, document process 10 (alone and/or in conjunction with another application) may provide pop-up window 276. In an illustrative example, pop-up window 276 may include formatting options, e.g., which may include options to modify a numbering style 278 and/or an indentation style 280 associated with provision 258. While pop-up window 276 is shown to include options for modifying formatting characteristics of provision 258, options may be included for modifying other characteristics of provision 258. Further, while pop-up window 276 is shown to include options for modifying numbering style and indentation of provision 258, options may be included for modifying other formatting characteristics (e.g., typeface, font size, capitalization, etc.). Accordingly, the illustrated embodiment should not be understood to limit the scope of the present disclosure.

In an illustrative embodiment, user 38 may choose, via onscreen pointer 274, the numbering style “a, b, c . . . ” from dropdown menu 282. In response to user 38 choosing numbering style “a, b, c . . . ” from dropdown menu 282, document process 10 may receive 208 a request to modify the first item (e.g., provision 258) included within the group (e.g., the group including the third hierarchical level of the document) by changing the number of provision 258 to lowercase alphabetical numbering format. Accordingly, modifying 202 the first item may be based on, at least in part, the received 208 request. It should be noted that the use of the term “first item” is intended to indicate any one of the items, without constraint on the order in which the item occurs in the group and/or the order in which the item was added to the group.

Document process 10 may further modify 204 all other items in the group based on the modified first item. For example, and referring also to FIG. 6, document process 10 may modify 204 all of the other items with the group (e.g., provisions 260, 268, 270 included within the third level hierarchical group) to include a lower case alphabetical numbering style based on, at least in part, the modification of provision 258. As such, all items in a third level hierarchical group throughout the document may be modified 204 to have the same numbering style. Even in a situation, as shown in FIG. 5, in which different items in the group may initially have different numbering styles (e.g., provisions 258-260 may initially have included lower case Roman numbering, and provisions 268-270 may initially have included Arabic numbering), document process 10 may modify the numbering of all items included within the group based on the modification of the first item. Accordingly, in the example embodiment, modifying all of the other items included within the group may include changing formatting characteristics associated with all of the items within the group based on and/or to match the formatting characteristics of the first item. As discussed above, characteristics or attributes other than formatting characteristics may also be modified.

Referring to FIG. 7, according to an embodiment document process 10 may determine 300 a hierarchical structure associated with a document. Document process 10 may also associate 302 the hierarchical structure with a plurality of elements of the document. Document process 10 may further generate 304 a map of the document. The map may include a plurality of links to one or more of the elements of the document.

In an embodiment, the document may include any type of document including a hierarchical structure that may be indicated by textual content and/or textual structure of the document. An example of a document that may include a hierarchical structure may include a legal agreement. However, the present disclosure may similarly be applicable to other documents having a hierarchical structure. As discussed above, document process 10 may determine 300 a hierarchical structure associated with a document. In an embodiment, determining 300 the hierarchical structure associated with the document may include processing 306 the document to determine the hierarchical structure. A document including a hierarchical structure indicated by the textual content and/or textual structure of the document may be processed 306 to determine the hierarchical structure in a manner as generally described above with reference to FIGS. 2 and 3. For example, document process 10 may process 306 the document to identify one or more indicators of hierarchy within the document, and may determine a hierarchical level associated with each of the indicators.

In some embodiments, determining 300 the hierarchical structure associated with the document may include accessing 308 structure data associated with the document. For example, in an embodiment, a document may have previously been processed, e.g., in a manner as described above. In some embodiments, hierarchical structure data may be associated with the document, e.g., in the form of metadata, or otherwise associated with the document. Further, in some embodiments, the document may otherwise include structure data associated with the document. In such an embodiment, document process 10 may access 308 the structure data associated with the document to determine the hierarchical structure associated with the document.

Document process 10 may also associate 302 the hierarchical structure with a plurality of elements of the document. For example, document process 10 may associate each of the plurality of elements of the document with a specific hierarchical level. Further, in an embodiment in which the document may include a legal agreement, the plurality of elements of the document may include one or more provisions of the legal agreement. In such an embodiment, documents process 10 may associate a specific hierarchical level with each of the provisions of the legal agreement.

Document process 10 may further generate 304 a map of the document. The map may include a plurality of links to one or more of the elements of the document having an associated hierarchical level. Additionally, document process 10 may generate a visual representation of the map. As shown in FIG. 8, document process 10 (alone and/or in conjunction with one or more additional applications) may generate user interface 350. User interface 350 may include a visual representation of the map of the document, which may include an arrangement of the plurality of links based on, at least in part, the hierarchical structure of the document. For example, in the illustrated embodiment, the map shown in user interface 350 may include a map of a legal agreement including a plurality of provisions. In an embodiment, the visual representation of the map may include a link associated with each of the provisions (e.g., which may each be associated with a hierarchical level or position within the hierarchical structure of the document). The links associated with each of the provisions of the document may be arranged in the visual representation in a manner that may be based on the hierarchical structure of the document. For example, the arrangement of the links within the visual representation may provide a visual indicator of the relative hierarchical position of each of the elements of the document associated with the links. While the illustrated arrangement of the links within the visual representation included in user interface 350 utilizes indentations to indicate relative hierarchical level associated with the various links, it will be appreciated that such an arrangement is only intended for the purpose of illustration, as other implementations may be utilized.

The plurality of links may include hyperlinks configured to navigate the document. For example, and as shown in FIG. 8, each of the section numbers and associated titles may include a hyperlink. A user (e.g., user 38 accessing document process 10 c 1 via personal computer 28) may select a link within user interface 350 (e.g., link “2.1 Dolor Sit Amet”) using onscreen pointer 274. Referring also to FIG. 9, in response to user 38 selecting the link “2.1 Dolor Sit Amet”, document process 10 may navigate to a portion of the document associated with the hyperlink. For example, document process 10 may display user interface 352 which may include the portion of the document associated with the hyperlink (namely section 2.1 of the agreement).

Referring also to FIG. 10, there is shown a diagrammatic view of computing system 12. While computing system 12 is shown in this figure, this is for illustrative purposes only and is not intended to be a limitation of this disclosure, as other configurations are possible. For example, any computing device capable of executing, in whole or in part, event monitoring process 10 may be substituted for computing device 12 within FIG. 10, examples of which may include but are not limited to client electronic devices 28, 30, 32, 34.

Computing system 12 may include microprocessor 400 configured to e.g., process data and execute instructions/code for event monitoring process 10. Microprocessor 400 may be coupled to storage device 16. As discussed above, examples of storage device 16 may include but are not limited to: a hard disk drive; a tape drive; an optical drive; a RAID device; an NAS device, a Storage Area Network, a random access memory (RAM); a read-only memory (ROM); and all forms of flash memory storage devices. JO controller 402 may be configured to couple microprocessor 400 with various devices, such as keyboard 406, mouse 408, USB ports (not shown), and printer ports (not shown). Display adaptor 410 may be configured to couple display 412 (e.g., a CRT or LCD monitor) with microprocessor 400, while network adapter 414 (e.g., an Ethernet adapter) may be configured to couple microprocessor 400 to network 14 (e.g., the Internet or a local area network).

As will be appreciated by one skilled in the art, the present disclosure may be embodied as a method (e.g., executing in whole or in part on computing device 12), a system (e.g., computing device 12), or a computer program product (e.g., encoded within storage device 16). Accordingly, the present disclosure may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, the present disclosure may take the form of a computer program product on a computer-usable storage medium (e.g., storage device 16) having computer-usable program code embodied in the medium.
